Swing GUI's integration with OpenCV

It is important to have rich graphical user interfaces while debugging or experimenting with computer vision projects, since some tasks might require a lot of tuning. This way, dealing with sliders, buttons, labels, and mouse events should be in the backpack of any computer vision researcher. Thankfully, you can work with all of these components in a relatively easy way in Swing. In this section, we will cover the most important parts of creating an application that loads an image and blurs it at several levels through a slider. This application also makes use of mouse events to highlight details in the image as well as a nice button to click and clear everything. The next screenshot gives us a good idea of how the application works. The code can be found in the opencv-gui project within the code bundle for this book.

The code to load an image is not new to us and can be found in the Displaying an image with Swing section. We will pay closer attention to...
